In this article, we explore the age-old question: is drinking 4-5 cups of tea daily detrimental to our health? Tea has long been a beloved beverage in many cultures, offering a comforting and refreshing break from the busyness of life. However, concerns have arisen regarding the potential negative effects of consuming large quantities of tea. Join us as we delve into the research, uncover the facts, and shed light on whether our beloved cup of tea might actually be harming our health.

Benefits of drinking tea

Prevents chronic diseases

Drinking tea has been linked to a reduced risk of chronic diseases such as heart disease, stroke, and certain types of cancer. The antioxidants found in tea, such as catechins, flavonoids, and polyphenols, help to neutralize harmful free radicals in the body. These free radicals can cause cellular damage and contribute to the development of chronic diseases. By regularly consuming tea, we can provide our bodies with a steady supply of antioxidants and help protect against the onset of these health conditions.

Boosts immune system

Tea is packed with beneficial compounds that can help boost our immune system. The polyphenols found in tea have been shown to have antibacterial, antiviral, and anti-inflammatory properties. These properties can help strengthen our immune response and protect against common illnesses such as the flu and colds. By including tea in our daily routine, we can support a healthy immune system and reduce the chances of falling ill.

Provides antioxidant protection

Tea is a rich source of antioxidants, which play a crucial role in protecting our cells from damage caused by oxidative stress. Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body, leading to cellular damage and increased risk of chronic diseases. The antioxidants in tea help to neutralize free radicals and prevent this damage from occurring. By regularly consuming tea, we can provide our bodies with a constant supply of antioxidants and support overall health and well-being.

Improves heart health

Research suggests that regularly drinking tea can have a positive impact on heart health. The flavonoids in tea have been shown to reduce the risk of heart disease by improving blood vessel function, reducing inflammation, and lowering blood pressure. Additionally, tea may help to reduce levels of LDL cholesterol (the “bad” cholesterol) while increasing HDL cholesterol (the “good” cholesterol). These combined effects can help to improve overall heart health and reduce the risk of cardiovascular diseases.

Aids digestion

Tea has long been known for its soothing and calming effects on the digestive system. Certain types of tea, such as peppermint and ginger tea, have been used for centuries to alleviate digestive discomfort and promote healthy digestion. These teas can help relax the muscles of the gastrointestinal tract, reduce gas and bloating, and soothe stomach cramps. By incorporating tea into our daily routine, we can support digestive health and alleviate common digestive issues.

Caffeine content in tea

Understanding caffeine

Caffeine is a natural stimulant that is found in varying amounts in tea, coffee, and other beverages. It acts on the central nervous system, increasing alertness and reducing fatigue. While caffeine can provide a temporary energy boost, it can also have some health implications, especially when consumed in excess.

Recommended caffeine intake

In the UK, the Food Standards Agency recommends a maximum daily caffeine intake of 400mg for adults. This is approximately the amount of caffeine found in four cups of brewed coffee. It is important to note that the caffeine content can vary depending on the type of tea and brewing method used.

Amount of caffeine in tea

The caffeine content in tea can vary depending on factors such as the type of tea, brewing time, and water temperature. Generally, black tea has the highest caffeine content, followed by green tea, oolong tea, and white tea. Herbal teas, such as chamomile or peppermint, are naturally caffeine-free. On average, a cup of black tea contains around 40-70mg of caffeine, while a cup of green tea contains approximately 20-45mg.

Impact of caffeine on health

While moderate caffeine consumption is generally considered safe for most individuals, excessive intake can lead to several health issues. These may include increased heart rate, restlessness, anxiety, difficulty sleeping, and gastrointestinal discomfort. It is important to be mindful of our caffeine intake and to consider individual sensitivities and health conditions when consuming tea or other caffeinated beverages.

Potential health risks


Although tea is primarily composed of water, it was once mistakenly believed that tea could dehydrate the body. However, recent research suggests that tea can be an effective way to hydrate the body. While tea does have a diuretic effect due to its caffeine content, this effect is relatively mild and does not outweigh the hydrating properties of tea.


As tea contains caffeine, consuming it in the evening may disrupt sleep patterns, especially for those who are sensitive to caffeine. For individuals who are prone to insomnia or sleep disturbances, it is recommended to avoid consuming caffeinated beverages close to bedtime and opt for caffeine-free herbal teas instead.

Anxiety and restlessness

Caffeine is a stimulant that can increase feelings of anxiety and restlessness, especially for individuals who are particularly sensitive to its effects. While these effects may vary from person to person, it is important to be aware of the impact of caffeine on our mental wellbeing and to consume tea in moderation if it tends to exacerbate feelings of anxiety or restlessness.

Gastrointestinal issues

In some individuals, consuming tea, especially on an empty stomach, can lead to gastrointestinal issues such as acid reflux, indigestion, or an upset stomach. This is more likely to occur in individuals who are prone to such issues or have a pre-existing gastrointestinal condition. If tea consumption triggers these symptoms, it may be necessary to reduce or avoid its intake.

Iron deficiency

Tea contains compounds called tannins that can inhibit the absorption of iron from plant-based sources. This means that individuals who rely on plant-based diets or have low iron levels should be cautious about consuming excessive amounts of tea. To mitigate this, it is advisable to consume tea between meals rather than with meals to minimize interference with iron absorption.

Bone health

Excessive tea consumption, especially “builder’s tea” with milk, has been linked to a potential increased risk of osteoporosis. This is due to the presence of compounds called oxalates in tea, which can interfere with calcium absorption. However, it is important to note that moderate tea consumption is unlikely to have a significant impact on bone health, especially when considering the other beneficial compounds found in tea.

The 4-5 cups of tea consumption

Benefits of moderate tea consumption

Moderate tea consumption, which refers to consuming 4-5 cups of tea daily, can provide several health benefits. Regularly drinking tea within this range can help increase our antioxidant intake, support heart health, boost the immune system, aid digestion, and provide a refreshing and enjoyable beverage option.

Disadvantages of excessive tea consumption

On the other hand, excessive tea consumption, especially when coupled with a high intake of caffeine, can lead to potential health risks such as insomnia, anxiety, gastrointestinal issues, and interference with iron absorption. It is important to be mindful of our tea intake and to balance it with other healthy lifestyle practices.

Recommended daily tea intake

Based on current research and expert recommendations, consuming 4-5 cups of tea, each containing around 200ml, is generally considered a safe and beneficial amount. However, it is important to consider individual factors such as sensitivity to caffeine, overall health condition, and potential interactions with medications when determining our optimal tea intake. Consulting a healthcare professional can provide personalized advice and guidance.
